To all whom it may concern:

Be it known that I, VERNON E. PARRISH. a citizen of the United States,and residing at Cupertino, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inMachines for Ridgin Land, of which the following is a spec' cation.

In certain methods of irrigating lands, particularly orchard lands andthe like, it is customary to throw up intersecting ridges of earth toform rectangular reservoirs whereby a given area of land may be floodedwith water independently of adjoining areas. In orchard irrigation theserectangular reservoirs are formed about each individual tree so thateven in small acreages a lar e number of these reservoirs are requir Itis the object of my invention to provide a device for ridging land forirrigation or other pu oses that will efiectivelform ridges of esiredhei ht and width; t at will cut through and ridge over crossing paths orroads; that can be maintained to form a required ridge in soft ground;and that can be nipped with a compacting device for the ridge after itis formed. A further object is to provide a compacting device to tooperate with said rid e forming machine, and to provide a mac ine of thecharacter indicated that will be simple in form and operation and highlyeflicient in its practical ap lication.

n the drawing:

Figure 1 is a plan view of the machine with the compacting devicemounted thereon.

Fig. 2 is a side elevation of the machine as shown in Fi 1.

Fig. 3 is a la ram illustrating the results secured by t e machineforming the basis of this invention.

Referring more particularly to the drawing, 1 indicates the frame of themachine provided with means at 2 for connecting the same to a tractorand having the rear cross member 3 raised a distance as shown so that itwill not engage the ridge formed by the machine. The rear member 3 andthe sides of frame 1 are connected by an ular portions 4 rovided with aseries 0 orifices 5 in whic are mounted hangers 6 carrying disks 7. Inbearings 8 on frame 1 are mounted bell-crank levers 9 carrying wheels 10on their outer ends and provided with handles 11 on their inner ends. At12 are shown notched sectors mounted on frame l adjacent levers 9whereby the said levers may be locked in a given position by means oflocking device 13.

In moving over solid ground such as a road, the lever 9 is thrown intothe position shown in Fig. 2 and locked in said position by means ofmechanism 12-13, with frame 1 and the parts carried thereby in theraised position shown. When, however, it is in use to form a ridge insoft ground the lever 9 is thrown forward and locked in a forwardposition such as indicated in dotted lines at 14. This movement operatesto lower frame 1 with relation to wheels 10, thereby causing disks 7 toenter the ground as shown in dotted lines at 7. The angular position ofthe disks as shown 0 crates to cut furrows as 15 and throw the soilremoved therefrom toward the draft line of the machine and substantiallyhigher than the general level of the ground as indicated at 16, thewidth of this rid e being determined by the position of disks on angularmembers 4 along which the said disks are adjustable by means of hangers6 and orifices 5.

In a device of this kind the disks 7 are so mounted and positioned thatwhen once set to cut for a given depth they will throw up a uniformlyregular ridge even though soil of varying character may be encountered.

It is desirable to appl some pressure to the side walls 17 of the ri geformed as hereinbefore described, whereby the same may be compacted, andlarge lumps of the soil broken up thereby preventing the formation ofopenings which would permit the passage of water throu h the ridge. Tooffset this desired result l provide a pair of disks 18 so positionedthat their inner surfaces bear against walls 17. These disks are held inposition by means of yoke 19 and arms 20, the latter bein connected toframe 1 as shown. As the ri ging machine moves forward the disks rotateon bearings 21 and press against walls 17 at the same time therebycombining a grinding action with pressure and eflicientlv shaplng andcompacting the said walls.

It is understood of course, that the machine may be used with or withoutthe com pasting device, and that changes in form,

proportions, details of construction and mode of operation may be madewithin the seoipe of the appendm. claims.

claim:

1: A- machine for ridging land including a frame, plowing means mountedupon each side thereof and within the same and an ranged to turn theplowed soil inwardly toward the draft line of the machine, a leveroperatively mounted upon each side of said frame forwardly of saidplows, each lever having its outer end extending bac1uvardl' insubstantial parallel relation to the said draft line to a point insubstantial alinement with said plows, a wheel operatively mounted oneach barkwardly extending por tion of said levers and adjacent one ofsaid plows, and means for locking each lever in a predeterminedposition.

2. A device for ridging land including a substantially open frame,supporting de vices for said frame, means for adjusting said frame withrelation to said supporting devices, plowing means mounted upon saidframe on each side of the draft line thereof and extending a distancewithin said frame whereby the plowed soil may be turned inwardly towardsaid draft line from both sides thereof, said frame having a raisedportion in the rear thereof to prevent engagement thereof with the ridgeraised by said JlOWS.

3. machine for ridging land including a frame, supporting devices forsaid frame,

means for adjusting said frame with relation to said supporting devices,plowing means mounted on said frame arranged to turn the plowed soilinto a ridge along the draft line of the machine, and means cooperatingwith said machine for compact ing the ridge formed by said machine, saidmeans comprising a frame connected to the rear of said first mentionedframe, and a pair of disks pivotally mounted thereon and having theirinner surfaces arranged to engage the sides of the ridge formed by saidmachine.
